A loudspeaker driver, which produces the sound of the frequency range from approximately 300 to 5000 hertz, is known as a midrange speaker. This operating range can vary considerably from one driver to the next. This gives the advantage of making system designing more flexible in choosing crossover points for the other drivers.

It is usually smaller than a woofer. It has a greater radiating surface area, compared to the typical tweeter. They are electro magnetic cone types or less frequently, electro dynamic dome types or compression horn drivers. The magnet structure of a midrange speaker is usually smaller, designed to produce most favorable response with much lesser power than the power required by a woofer. The power handling rate is also comparatively less. A few midrange speakers are electrostatic loudspeakers, Heil drivers, planar magnetic drivers, or ribbon drivers.

Dispersion, the extent to which a sound emitter yields acoustic radiation over a given area is one of the prime objectives in designing a midrange speaker. Its portion of the audio spectrum has a much more directional character than woofers. Midrange speakers, which are developed by further improvising a woofer, will usually have a closed back design. This is done to prevent interference from the woofer internal backwave. This interference is usually due to the intermodulation distortion. A high quality midrange driver is capable of low distortion reproduction.

Midrange speakers are usually used in three way multi driver speaker systems. There is a special consideration involved in the acoustic join among the midrange and both the low frequency and the high frequency, which are the woofer and the tweeter respectively. The nature of the drivers on both of the sides of the midrange, and the midrange itself, affect the crossover circuitry, which is required to provide quality performance of the speaker system.

Midrange speaker is commonly found in a car system. You can find a woofer in a box in the rear, tweeters mounted on the dash panel and the midrange in the side or the door panels. This is done due to its surround applications.

Placement of these midrange drivers on the enclosure baffle is significant. This depends on the size of the cabinet, the crossover frequency both low mid or mid high, the materials surrounding the midrange and tweeter drivers on the baffle and the front to back location of each driver acoustic center with respect to the others. With the grills or covers, each of these aspects affect the presentation of both midrange and tweeter drivers and so the loudspeaker system as a whole. The term, often used in design circles for some of these effects, is the baffle step effect.

The role of a Midrange speaker is to handle the most significant part of the audible sound spectrum. This is the main region where the most basic sound produced by musical instruments and human voice lie. This region contains most of the sounds, which are the most familiar to the human ears, and where any differences from faithful reproduction will be most easily observed.
